Title: Correction for missing or deleted symbols using parity check equations
Inventor: TOMLINSON MARTIN
IPC: G06F11/10
Filed: 2004-12-22
Abstract: In many communications systems, broadcasting systems and storage systems, information is encoded as a sequence of symbols. The total number of symbols transmitted or stored is denoted by n, and these are obtained by encoding k information symbols using parity check equations from an error correcting code (ECC). The present invention allows the k information symbols to be recovered before all n symbols have been received or read, thereby compensating for missing symbols and allowing faster access to the information. Three decoding methods using parity check equations to recover missing symbols are described, each of a different degree of complexity. It is shown that the present invention can cope with a higher number of missing symbols than the current state of the art.

Title: Injection device with a trigger locking mechanism
Inventor: HABESHAW ROSEMARY LOUISE
IPC: A61M5/20
Filed: 2005-04-06
Abstract: An injection device 110 is provided which includes a syringe having a discharge nozzle 122. The syringe is movable between a retracted position in which the discharge nozzle is contained within the housing 112 and an extended position in which the discharge nozzle 122 extends from the housing 112.

Title: Plastically deforming and radially expanding an expandable tubular member
Inventor: RING LEV
IPC: E21B23/00
Filed: 2002-08-13
Abstract: Apparatus 300 is inserted into a tubular member 120 which causes an upper end 120b of the tubular member to impact collets and compress springs so as to apply axial biasing forces to a split ring collar 330 and expansion cone segments 325. The segments 325 are thus maintained in a position that is less than the inside diameter of the tubular member 120. Also an axial biasing force is applied to a tubular sleeve to prevent it from covering a radial passage 315d in a tubular support member 315. Thus, fluids within the interior 315a of the tubular support member 315 may pass through the radial passage 315d into the annulus between the apparatus 300 and the tubular member 120 thereby preventing over pressurization of the annulus. After positioning the apparatus 300 beyond lower end 120c of the tubular member 120, the apparatus is then repositioned partially back within the tubular member 120. During the re-insertion, the lower end 120c of the tubular member impacts the collets and compresses the springs to seal off the radial passage 315d and drive the expansion cone segments 325 up expansion cone support body 315i. An upward axial force is then applied to the tubular support member 315 to radially expand and plastically deform the tubular member 120.

Title: A method for the generation of water with reduced ionic solutes
Inventor: MONRO PHILIP PETER
IPC: B01D61/00
Filed: 2006-10-21
Abstract: A device comprising one or more proximal and distal chambers separated by a selectively permeable membrane which has a restricted but not absolute restriction of porosity with respect to dissolved solutes. This device is designed to generate a solution with a reduction in the concentration of these solutes distal to this membrane by the processes of forward and/or reverse osmosis. Such devices can further utilize those solutes initially present on the proximal side of the membrane but which have crossed the membrane themselves so that they then act as osmotic drivers and so facilitate the further movement of solutes across the membrane.

Title: Apparatus and method for lung analysis
Inventor: WILKINSON MALCOLM HOWARD
IPC: G01S15/88
Filed: 2005-06-02
Abstract: An apparatus and method of detecting COPD and in particular, emphysema utilizes a change in acoustic transmission characteristics of a lung due to e.g. the appearance of fenestrae (perforations) in the alveoli of the lung. The use of acoustic signals may provide good sensitivity to the existence of alveolar fenestrae, even for microscopic emphysema, and the appearance and increase in fenestrae may be determined by monitoring acoustic transmission characteristics such as, for example, an increase in acoustic signal velocity and velocity dispersion, and/or a change in attenuation. A transmitter may be located in e.g. the supra-clavicular space and receivers may be mounted on the chest. Measurements may be correlated between pairs of receivers to determine acoustic transmission profiles.
Patent GB-2448117-A (GB)
Title: Forward power converter controller
Inventor: JACQUES RUSSELL
IPC: H02M1/42
Filed: 2007-03-30
Abstract: A resonant discontinuous forward converter (RDFC) comprises a switch such as transistor 1004 to cyclically switch DC power to polarity matched transformer 1002, and provides a DC output. A controller 1040 switches switch 1004 on when the rate of change of primary voltage, dv/dt, reduces to below a threshold, adjacent a minimum of the primary voltage, when it is close to 0V. A comparator circuit (fig 5) may detect the primary voltage rate of change by monitoring current in a capacitor 1006 connected to either primary 1002p or an auxiliary winding 1004 and which may also support resonance in transformer 1002, to detect a leading signal (fig 6, Sr) and a trailing signal (fig 6, Sf). Either the time of switch off or the leading signal (fig 6, Sr), together with the trailing signal (fig 6, Sf) can be used to estimate a resonance period that is used to determine an on period of switch 1004. The effects of multiple transitions of signals (fig 8b, Sr,Sf) arising from noise, leakage inductance and stray inductance may be avoided by ignoring transitions during periods Sf(a) and Sf(b) which can be fixed or a fraction of the estimated resonance period. Controller 1040 may be implemented as an integrated circuit and provides efficient switching and reduced electromagnetic interference (EMI).
